title: [Expression of FLT3-ITD oncogene confers mice progenitor B-cells BAF3 sensitivity to the ribonuclease binase cytotoxic action].
abstract: Acute myeloid leukemia is the most common acute leukemia affecting adults, and its incidence increases with age. Along with chromosomal translocations in leukemic cells mutations in the genes of receptor tyrosine kinases KIT and FLT3 were found with a high frequency. Here we show that transgenic progenitor of B-cells BAF3/FLT3-ITD are much more sensitive to the ribonuclease binase cytotoxic effects than the original BAF3 cells. The principal difference between BAF3/FLT3-ITD and the original BAF3 cells is the expression of FLT3-ITD oncogene, which leads to a change in the normal cell signaling pathways. Earlier, we described a similar effect for the cytotoxic action of binase on Kasumi-1 and FDC-P1-N822K cells, which express the activated KIT-N822K oncogene. Increased binase cytotoxicity toward the cells, expressing FLT3-ITD oncogene, suggests that, as in the case of FDC-P1 cells, transduced by KIT oncogene, the expression of an activated oncogene determines the sensitivity of cells to binase.
